This quasi-experimental study investigated the effectiveness of integrating Information and Communication Technology into instructional practices on students' academic performance in government secondary schools within Ilala District, Tanzania. Specifically, the study compared traditional teacher-centered instruction with two ICT-integrated strategies: simulation-based learning and online search-based learning. Four instructional groups were analyzed using pretests and post-tests to measure performance gains. Findings indicate that simulation-based learning yielded the highest performance (M = 62.84), significantly outperforming both lecture-based instruction (M = 37.91) and online search-based learning (M = 57.07). Independent samples t-tests confirmed these differences were statistically significant (p < .001), with large effect sizes. Additionally, a one-way ANOVA revealed significant performance variation across groups, F (3,196) = 28.30, p < .001, further validating the impact of ICT on learning outcomes. The study demonstrates that incorporating digital content fosters greater student engagement, comprehension, and test performance, even within limited instructional periods. Recommendations include expanded investment in ICT infrastructure, and curriculum reform to embed digital competencies. Strategic implementation of the National Digital Education Strategy (2024/25–2029/30) is also essential. Professional development for teachers should be prioritized to build confidence and skill in using ICT tools effectively. Post-hoc findings suggest simulation-based instruction offers the most consistent gains, making it a strong option to be used in schools across the country. The study advocates for intentional and inclusive adoption of ICT to cultivate an engaging, equitable, and future-ready educational environment.
